Really cute and really fun, even if it doesn't fit the theme exactly as intended. The only thing I would suggest to get a better experience is making the crosses reset their position each time a new marble appears as inserting randomness really feel antithetical to the rest of the game design which is making small adjustments to a relatively predictable rute for the marble. I also thank you for including the skip level and go back buttons as not many games take care to make travel between levels even posible.
